| This is the original composition (mod. Fe source) as published by E. Vacin |
| and F.W. Went in Botanical Gazette 110: 605-613. The medium was supposed |
| to have an improved pH stability for sowing tropical orchids. It is still widely |
| used today, but usually with a modified Fe-source and addition of organic |
| compounds like vitamins, organic nitrogen sources and undefined complex |
| additives. A typical application is in propagation of Oriental cymbidiums. |
| This medium has a modified Fe-source that insures similar Fe-quantity |
| with slightly improved availability and a reduced quantity of high gel-strength |
| agar to insure good gel constitution. |
